1 Microsoft - Cheyenne Board of Public Utilities Biogas CHP Demonstration Project Presented By: Sean James - Microsoft Ryan Smith - BOPU Todd Lovell - Jacobs E.B. Jensen - Jacobs

2 Sean James o Microsoft - Advanced Data Center Development Group Sr. Research Program Manager Sean James is responsible for research and developing new datacenter technology for Microsoft s Global Foundation Services (GFS) group. GFS provides the foundational cloud infrastructure for over 200 Microsoft online and cloud services for consumers and businesses worldwide. Sean drives new datacenter technology for Microsoft s next generation data centers including the evaluation, development, and testing. Sean joined Microsoft in 2007 to manage one of Microsoft s data centers. Later, he joined the construction team and oversaw the design and building of new Microsoft data centers. Prior to joining Microsoft, Sean worked in data center management overseeing the dayto-day maintenance and repair operations for both IT hardware and critical infrastructure, such as backup generators and electrical switchgear. Prior to joining Microsoft, Sean served in the US Navy Submarine Fleet as an electrician.

3 Ryan Smith Cheyenne - Board of Public Utilities (BOPU) Plant Supervisor Operations & Maintenance Ryan Smith has been in wastewater treatment for 7 years, the last 5 with the BOPU in his current position.

4 Todd Lovell Jacobs Project Management Company Senior Projects Manager Mr. Lovell has 30 years of diverse project management experience, 6 years with Jacobs, the last 4 working in alternative energy solutions, including multiple CHP business projects and numerous gas to energy projects utilizing fuel cell technologies.

5 E.B. Jensen, P.E., CEM Jacobs Engineering Director - Power & Energy Mr. Jensen has been with Jacobs for over 11 years and has been in the CHP business for over 25 years. He has been involved in numerous biogas gas to energy projects and projects involving fuel cells - both simple cycle and ones in CHP configurations.

6 Sean James Project Background The rising demand for online services is driving the need to identify and development new sources of energy In May 2012, Microsoft made a commitment to make our operations carbon neutral; including datacenters In addition to renewable project investments and internal carbon tax, we were looking for innovative sources of clean energy

7 Sean James Project Background Based on the benefits of waste to energy projects, we invited proposals from various sewer utilities. Cheyenne LEADS and Western Research Institute coordinated the winning proposal. The team included: City of Cheyenne Cheyenne Board of Public Utilities Cheyenne Light Fuel & Power FuelCell Energy The University of Wyoming Wyoming Business Council

8 Sean James Project Background Microsoft provided matching funds to the Wyoming Business Counsel grant of $1.5M to fund infrastructure upgrades to the BOPU site In addition, Microsoft provided a server container and purchased a 300kW fuel cell from FuelCell Energy FuelCell Energy also contributed $700k in-kind

9 Ryan Smith Why BOPU participated BOPU was interested in the project because: It gave the facility the opportunity to implement a new CHP technology that would not have been achieved with public only funds. By installing such a system with sophisticated monitoring systems, the plant would be able to better monitor and analyze the plants operational behaviors. Through the fuel cell plant power and thermal outputs, it was expected the Wastewater treatment plant would see a decrease in utility electric and natural gas consumption.

10 Ryan Smith Wastewater Treatment Plant The Wastewater treatment plant has been in operations since 1975 and is designed for a daily wastewater inlet capacity of 10.5 million gallons per day. The plant consumes on average kwhrs of electricity per month. The plant consumes on average decatherms of natural gas on a monthly basis primarily for use in sludge heating.

11 Todd Lovell The Project Management The project execution approach was thru an EPC arrangement with Fuel Cell Energy performing as both equipment supplier and turnkey EPC provider. Jacobs performed as Microsoft's PM/CM provider and Owner's Engineer. As PM - Jacobs assisted MS with the receipt and distribution of public funds from Wyoming Business Council/City of Cheyenne.

12 Todd Lovell The Project Management Jacobs PM, acting as the MS representative, also provided the PM/CM services : Subject Matter Expertise Infrastructure & System Design Review as Owner s Engineer Quality Assurance (Owners Rep) - Design & Construction Coordination of stakeholders BOPU Microsoft LEADS City of Cheyenne WRI UWO FCE EPC Team Project financial tracking

18 Test Data - thru Sept 2014 Project is still in construction (HRU & ADG) Operations to date on Fuel Cell with natural gas. The operational testing of the fuel cell has enabled the Wastewater treatment plant to gain a better understanding of how the operations of high power consuming equipment can impact the overall electric power demand for the entire facility. Thru the testing to date, the peak load reduction has been identified thru a modification to the plant operator's methodology for equipment sequencing.
